Close-upimage taken at around 5:26 am ACDST, Infinity to infinity focusing, Canon IXUS through a 20 mm eyepiece on a 4" unguided Newtonian. As Spica came close to the Moon, I changed the zoom factor on the IXUS to 3x get a close-up view.

Overlay of 9 close-up images using ImageJ, because the scope was unguided, the images don't register very well. Bumped the scope at the last minute, so I missed Spica going behind the Moon.
